configure-formatting

configure-formatting is a skill for Claude Code, Codex from laurigates/claude-plugins. It costs 51 tokens per session (2,320 once invoked), scanned A, original, MIT.

A setup guide for automatic code formatting with Biome, Ruff, or rustfmt. Formatters rewrite code into a consistent style without changing its intended behavior.

In plain words
What is it for?
Use it to configure formatting, replace Prettier or Black, add format-on-save, standardize a monorepo, or check formatting in CI.
Why use it?
It reduces style differences and avoids formatting disputes or failed checks across JavaScript, TypeScript, JSON, CSS, Python, and Rust files.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

configure-formatting scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/configure-formatting.sh, scripts/tests/test-configure-formatting.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

/configure:formatting

Check and configure code formatting tools against modern best practices.

When to Use This Skill

Use this skill when... Use another approach when...
Setting up Biome, Ruff format, or rustfmt for a project Running an existing formatter (biome format, ruff format)
Migrating from Prettier or ESLint to Biome, or Black to Ruff Fixing individual formatting issues in specific files
Auditing formatter configuration for completeness and best practices Configuring linting rules (/configure:linting instead)
Adding format-on-save and CI format checks Setting up pre-commit hooks only (/configure:pre-commit instead)
Standardizing formatting settings across a monorepo Editing .editorconfig or .vscode/settings.json manually

Context

  • Biome config: !find . -maxdepth 1 -name \'biome.json\'
  • Prettier config: !find . -maxdepth 1 \( -name '.prettierrc*' -o -name 'prettier.config.*' \)
  • Ruff config: !find . -maxdepth 1 -name 'pyproject.toml' -exec grep -l 'tool.ruff.format' {} +
  • Black config: !find . -maxdepth 1 -name 'pyproject.toml' -exec grep -l 'tool.black' {} +
  • Rustfmt config: !find . -maxdepth 1 \( -name 'rustfmt.toml' -o -name '.rustfmt.toml' \)
  • EditorConfig: !find . -maxdepth 1 -name \'.editorconfig\'
  • Package JSON: !find . -maxdepth 1 -name \'package.json\'
  • Python project: !find . -maxdepth 1 -name \'pyproject.toml\'

  • Pre-commit: !find . -maxdepth 1 -name \'.pre-commit-config.yaml\'
  • Project standards: !find . -maxdepth 1 -name \'.project-standards.yaml\'

Parameters

Parse from $ARGUMENTS:

  • --check-only: Report compliance status without modifications
  • --fix: Apply all fixes automatically without prompting
  • --formatter <formatter>: Override formatter detection (biome, ruff, rustfmt)

Version Checking

CRITICAL: Before flagging outdated formatters, verify latest releases using WebSearch or WebFetch:

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
